Solutions

Expert Solution

1 - 500 cc D5W over 4 hours with a drop factor of 12.

gtt/min

cc / hr =

Ans --

500 / 4 =125ml/ hr

cc / hr =  125 cc / hr is the answer

Drop factor = 12

1 hr = 60 min

gtts / hr is

125 x 12 / 60 = 25 gtts / hr

  

  

2 - 1000 cc D5W over 12 hours with drop factor 15

gtt / min

cc / hr =

Ans -

1000 / 12 = 83.33 cc / hr

83.33 cc / hr is the answer

Drop factor = 15

1 hr = 60 min

gtts / ml is

83.33 x 15 / 60 = 20.833 gtts / min

3 -  3000 cc NS over 24 hours with a drop factor of 20 gtt/ min

cc / hr =

Ans --

3000 / 24 = 125 ml/ hr

125 ml / hr is the answer

Drop factor = 20

1 hr = 60 min

gtts / ml is

125 x 20 / 60 = 41.67 gtts / min

4 - 115 cc NS IVPB over 45 minutes with drop factor of 12.

gtts/min:

cc/hr:

Ans -

115 / 45 = 2.56 ml/ min

1 hr = 60 min

ie 2.56 x 60 = 153. 6 ml / hr

Answer is 153.6 ml / hr

gtts / ml is

Drop factor = 12

gtts/ ml is

153.6 x 12 / 60 = 30. 72 gtts / min

5 - 300 cc packed red blood cells (RBCs) over 3 hours with a drop factor of 10.

gtts/min:

Ans -

ml / hr is

300 / 3 = 100 ml / hr

Drop factor is 10

1 hr = 60 min

ie 100 x 10 / 60 = 16.67 gtt / min

Answer is 16.67 gtts / min

6 - 250 cc NS over 1 ½ hours with a drop factor of 60.

gtts/min:

1. 30 hr = 90 min

Drop factor = 60

ie 250 x 60 / 90 = 166 gtts / min

7 - 50 cc Albumin over 20 minutes with a drop factor of 60.

gtts/min

ml / min = 50 / 20 =2.5 ml

1 hr = 60 min

ie 2.5 x 60 = 150 ml / hr

gtts min =

150 x 60 / 60 = 150 gtts / min

8 -  750 cc NS over 6 hours with drop factor of 15.

gtts/min

  cc/hr:

750 / 6 = 125 ml / hr

gtts / min = 125 x 15 / 60

31.25 gtts/ min

9 - 1000 cc NS over 12 hours with drop factor of 12.

gtts/min:

cc/hr :

1000 / 12 = 83.33 ml / hr

gtts/ min = 83.33 x 12 / 60

16.67gtts / min

9 - 500 cc NS over 24 hours with drop factor of 10.

gtts/min:

cc/hr

500 / 24 = 20.83 ml / hr

gtts/ ml = 20.83 x 10 / 60

3.472 gtts/ min

10 - 2 Units of whole blood (700 cc) over 8 hours with drop factor of 15.

gtts/min:

cc/hr:

700 / 8 = 87.5 ml / hr

gtts / min = 87.5 x 15 / 60

21.88 gtts / min

11 - 250 cc Rocephin over 2 hours with drop factor of 15.

gtts/min:

cc/hr

250 / 2 = 125 ml / hr

gtts/ min = 125 x 15 / 60
